| # Writing High-Quality Software Documentation with MDX | |
| **A practical guide for developers and AI assistants** | |
| Good documentation can make the difference between a successful software project and one that struggles to find or keep users. When technical users can’t figure out how to use your product, they won’t remain users—no matter how amazing the software is (@Don't Skimp on Documentation | Twilio). Poor docs don’t just frustrate readers; they create “operational debt” in the form of support burdens and lost adoption (@Don't Skimp on Documentation | Twilio). In fact, bad or missing documentation often *feel* the same to a user (@Good Docs Take Great Effort | er4hn), wasting their time and forcing them to ask maintainers basic questions. On the other hand, great documentation empowers users to get started quickly and solve problems on their own (@Good Docs Take Great Effort | er4hn). This guide will cover documentation philosophy, types of docs (per the Diátaxis framework), writing style tips, formatting and examples (using MDX), maintenance strategies (leveraging Mintlify), common pitfalls, and more – all structured like a high-quality documentation itself. Whether you’re a developer or an AI assistant helping to write docs, these best practices will help you create clear, user-friendly, and maintainable documentation, specifically tailored for the MDX and Mintlify environment. | |
| ## Philosophy: Documentation as a First-Class Component | |
| High-quality documentation **is not an afterthought – it’s part of the product**. Treat docs as a core feature that deserves time and effort, just like the code. As cURL’s maintainer Daniel Stenberg puts it, documentation should *never* be a “second-tier component” but a **“crucial and important foundation”** that allows users to use, trust, and rely on your product (@Making world-class docs takes effort | daniel.haxx.se). Writing excellent docs takes significant effort and iteration, but it pays off through better user adoption and less support load (@Good Docs Take Great Effort | er4hn) (@Good Docs Take Great Effort | er4hn). Here are key principles to guide your approach: | |
| - **User-Centric Perspective:** Always start with the user’s needs and point of view. Understand who your audience is, what they’re trying to achieve, and how they look for answers (@Don't Skimp on Documentation | Twilio). Documentation succeeds when it helps *users* accomplish their goals or learn effectively. Empathize with their context and skill level. (We’ll formalize audience and use-cases via Diátaxis in the next section.) | |
| - **The Diátaxis Mindset:** Not all documentation is the same. A common mistake is to treat docs as one monolith. Instead, recognize the different documentation types (Tutorials, How-To Guides, Reference, Explanations) and their distinct purposes (@Diátaxis). Embracing this structure helps ensure you address all user needs without confusing them (more on this below). In short: **different parts of your docs should serve different goals**, from teaching newcomers to providing authoritative reference. | |
| - **Documentation-First Development:** Incorporate documentation writing into your development cycle *early*, not at the last minute. In fact, consider writing initial docs or a README **before** coding the feature – an approach known as “Readme Driven Development” (@Don't Skimp on Documentation | Twilio). This forces you to clarify the API/design and ensures you’re excited (not burned out) when writing the docs (@Don't Skimp on Documentation | Twilio). If you leave docs until the end, they “won’t be as awesome as they should be” (@Don't Skimp on Documentation | Twilio). Many developers find that writing docs first can even improve the design of the software by revealing unclear areas upfront (@Don't Skimp on Documentation | Twilio). | |
| - **Documentation is Part of Definition of Done:** Just as you wouldn’t ship a feature without testing it, you shouldn’t ship it without appropriate documentation (@Good Docs Take Great Effort | er4hn). Make documentation updates a required step in your workflow (code reviews, checklists, etc.). When a feature or API changes, its docs should be updated in the *same pull request* or release. By treating docs with the same importance as code, you prevent knowledge from drifting. Some teams even configure tooling to **require** docs changes alongside code changes (or at least a confirmation that docs were reviewed) (@Good Docs Take Great Effort | er4hn). | |
| - **Continuous Improvement:** Documentation is never “done.” Good projects iterate on docs continuously. Over time, refine guides based on user feedback, add clarifications, and polish wording. “No documentation is perfect at first attempt, but after numerous iterations chances are it is better… and we are never done – documentation can always be improved,” writes Stenberg (@Making world-class docs takes effort | daniel.haxx.se). Approach docs as a living document that evolves with your product. Regularly audit and prune them; outdated or redundant content should be removed or rewritten to stay useful. | |
| - **Equal Platform for Users:** Remember that many users will encounter your documentation *outside* of your website’s main page – often landing on a specific page via a search engine. In Twilio’s case, over 50% of doc visitors came straight from Google (@Don't Skimp on Documentation | Twilio). This means each documentation page should be a **self-contained unit of awesomeness** (@Don't Skimp on Documentation | Twilio). Don’t assume a reader has read any other page or some “intro” first – provide necessary context or links on every page. Also, think about discoverability (SEO): use descriptive titles and headings (one `<h1>` that clearly describes the page (@Don't Skimp on Documentation | Twilio)), meaningful link text (e.g. *“see the SMS sending guide”* instead of *“click here”* (@Don't Skimp on Documentation | Twilio)), and include keywords a user might search for. Mintlify helps with this by automatically generating SEO-friendly URLs and metadata. Ultimately, if users can’t *find* or navigate your docs easily, those docs aren’t serving their purpose (@Making world-class docs takes effort | daniel.haxx.se). Good documentation is easily searchable, accessible, and browsable. | |
| In summary, the philosophy of great documentation is **user-first and quality-first**. Recognize that writing docs is an investment that repays itself by enabling users (and future maintainers) and reducing support friction. Dedicate time and effort to it as you would for any feature, and adopt a structured, user-oriented approach from the start. | |
| ## Documentation Types: The Diátaxis Framework | |
| Not all documentation readers are looking for the same thing. One might be a beginner trying to learn the tool from scratch, another might be an experienced user quickly checking a function’s syntax. A single document rarely serves both well. The **Diátaxis framework** provides a clear division of documentation into four categories, each serving a distinct purpose (@Diátaxis). By structuring your docs into these types, you ensure every user can find the kind of information they need, presented in the optimal way (@Diátaxis). The four types are: **Tutorials, How-To Guides, Reference,** and **Explanations.** Here’s what each means and how to approach them: | |
| ### 1. Tutorials (Learning-Oriented Guides) | |
| **What it is:** A *tutorial* is a hands-on lesson designed to **teach** a new user how to achieve something with your software. It is **learning-oriented** – more about guiding the user through a meaningful exercise than accomplishing a real-world task quickly (@Tutorials - Diátaxis). In a tutorial, the user “learns by doing” in a controlled, example scenario (@Tutorials - Diátaxis). The goal is to build the user’s confidence and foundational knowledge. | |
| **How to write:** Assume the reader is a beginner (at least with respect to the topic at hand). Provide step-by-step instructions, with each step explained, and minimal assumed prior knowledge (aside from prerequisites you explicitly state). A tutorial should have a clear end goal (e.g. “Build and run a simple Todo API”) and the reader should achieve something tangible by the end. Focus on teaching *concepts through practice*, not exhaustive detail. For example, a Django web framework tutorial might walk through creating a small app, during which the reader learns basic concepts (MVC, routing) implicitly. Keep the tone encouraging and avoid digressions – if complex concepts are involved, the tutorial might instruct actions first, deferring deep explanations for later. As Diátaxis notes, *“its purpose is not to help the user get something done, but to help them learn”* (@Tutorials - Diátaxis). | |
| **Tips:** | |
| - Provide all necessary setup steps (installations, environment prep) so that a novice can follow along without frustration. | |
| - Show code in full context. Even if it seems obvious to you, include import statements, file names, or configuration needed to run the example, because the user might be copying blindly (indeed, many will copy-paste code exactly as given (@Don't Skimp on Documentation | Twilio)). **Use MDX components like `<Code>` to display code blocks with syntax highlighting.** | |
| - Aim for a small, contained project that illustrates key usage. The user should feel “I did it!” at the end – this builds confidence (@Tutorials - Diátaxis). | |
| - Avoid overwhelming detail or covering every edge case. Stay focused on the learning path; reference material can be linked for deeper info. **Use Mintlify's linking features to easily cross-reference other pages.** | |
| - Assume the reader will **not** remember everything. The goal is exposure and a successful experience, not mastery in one pass. Don’t quiz them; let them accomplish something positive. | |
| ### 2. How-To Guides (Task-Oriented Recipes) | |
| **What it is:** A *how-to guide* is a **goal-oriented** set of instructions for achieving a specific *real-world task or problem* (@How-to guides - Diátaxis). It helps the user **get something done** in a correct, efficient way (@How-to guides - Diátaxis). Unlike tutorials (which are learning exercises), how-to guides assume the user has a basic familiarity with the product and now needs to accomplish a particular goal. These are the “recipes” of your documentation. For example: *“How to add user authentication to your app,” “How to configure a Docker container for the service,” “How to generate an API key.”* | |
| **How to write:** Write how-to guides from the *user’s perspective*, anchored on the user’s goal or problem to solve (@How-to guides - Diátaxis). Each guide should answer a specific “How do I…?” question that a user would actually ask. It should provide a sequence of steps or an outline of solution, **focusing on the task** rather than the underlying theory. For instance, *“How to integrate OAuth login”* might assume the user already knows what OAuth is (or has access to explanation docs if needed), and jump straight into the steps with your product: (1) registering an application, (2) configuring callbacks, (3) exchanging tokens, etc. All steps should be ordered and clear, with necessary code or command snippets included. | |
| Make sure the scope is well-defined – a how-to guide should not try to cover too broad a scenario. (If you find yourself writing *“How to build a full e-commerce website”* as a single guide, that’s likely too large and unfocused; break it into smaller tasks or provide a tutorial instead (@How-to guides - Diátaxis).) A good how-to is like a recipe: it lists prerequisites (ingredients), then instructions to achieve the end result. | |
| **Tips:** | |
| - **Be task-specific:** The title and content should address a concrete use-case. This not only helps users accomplish things, but the list of how-to guides itself showcases your product’s capabilities (an extensive, relevant how-to section reassures users what your product can do (@How-to guides - Diátaxis)). | |
| - **Prerequisites:** State what the user should know or have beforehand (e.g. “Before starting, you should have X installed and a project set up as in the Tutorial”). | |
| - **Step-by-step clarity:** Numbered steps work well for procedures. Use clear, action-oriented language for each step (e.g. “Open the **Settings** page and click **+ New Key**”). | |
| - **Focus on the user’s goal:** Don’t describe internal system operations unless needed; keep the guide about what *the user* needs to do and see. For example, rather than “Our system will generate a token using X algorithm,” say “**You will receive a token** that you can use to authenticate subsequent requests.” | |
| - **Safety and correctness:** How-to’s often involve configurations or operations. Include any necessary warnings or gotchas (“Make sure to save the secret; you won’t be able to view it again”) so the user accomplishes the task *safely* and *correctly* (@How-to guides - Diátaxis). **Use Mintlify's `<Callout>` component for warnings and important notes.** | |
| - **Link to reference:** If details get complex (e.g. lots of parameters), you can instruct the user through the basic path and then link to reference docs for further options. Keep the primary flow as straightforward as possible. **Mintlify's automatic linking makes this seamless.** | |
| ### 3. Reference (Technical Reference) | |
| **What it is:** Reference documentation is the **information-oriented** listing of facts about the product’s internals – essentially the “source of truth” for APIs, functions, classes, commands, CLIs, configuration options, etc. (@Reference - Diátaxis) (@Reference - Diátaxis). It’s not meant to be read linearly; it’s meant to be *consulted* when needed. A reference is typically organized for quick lookup (alphabetical, by module, by command, etc.) and aims to be **comprehensive and precise**. For software, this often includes API docs, REST endpoint specs, object models, and so on. | |
| **How to write:** In reference material, **neutral, factual description** is key (@Reference - Diátaxis) (@Reference - Diátaxis). Document *what each thing is* and *how it behaves*, in a concise and unambiguous way. Avoid narrative, tutorials, or big explanations here – the reader likely comes with a specific question like “What parameters does function X accept and what do they mean?” or “What does error code 40305 indicate?” Write each entry to **stand on its own** with clear definition of the item, its syntax, parameters, return values, side effects, error conditions, and examples of usage if applicable. For an API function, this might mean: function signature, description, arguments (types and meaning), return value, exceptions thrown, and a short example. For a configuration file reference, it could be each setting and the allowed values, default, and effect. | |
| Because reference guides are product-led (structured by the software’s components, not user tasks (@Reference - Diátaxis)), **make sure to include everything**. Every public API or user-facing feature should be documented here (if something is omitted, advanced users will notice and might even resort to reading source code, which is a failure of docs (@Making world-class docs takes effort | daniel.haxx.se)). Note version information for long-lived projects – e.g., “*(Added in v4.2)*” for a parameter, so users know if something is available in their version (@Making world-class docs takes effort | daniel.haxx.se). **Mintlify's versioning feature is crucial here.** | |
| **Tips:** | |
| - **Authoritative and unambiguous:** Reference material should be 100% correct and leave no uncertainty (@Reference - Diátaxis). Use precise terminology (e.g., say “AES-256-GCM encryption” instead of “uses encryption” to be clear (@Good Docs Take Great Effort | er4hn)). If a term could be unfamiliar, briefly define it or link to an explanation. | |
| - **No step-by-step or narrative:** This is not the place for guiding the user through processes or discussing “why.” If you find instructions creeping in (e.g. “First do X, then Y”), that might belong in a how-to guide. Reference can describe *what* something does or *how it works*, but generally not *how to accomplish a user goal* (with the exception of brief usage notes). | |
| - **Consistency in format:** Use a consistent template for each reference entry. For example, all functions could have the sections: **Name**, **Synopsis** (or signature), **Description**, **Example**, **Errors**, etc. Consistent ordering of information in each entry helps users find what they need quickly (@Making world-class docs takes effort | daniel.haxx.se). In fact, enforcing a standard structure (even via automated checks) is a good practice to ensure completeness and uniformity (@Making world-class docs takes effort | daniel.haxx.se). | |
| - **Auto-generation with care:** Some reference docs (like API docs from code comments) can be auto-generated, which ensures accuracy to the code (@Reference - Diátaxis). Use these tools (and Mintlify's API Playground) to populate the basics, but **don’t rely on them exclusively**. The best documentation often isn’t *just* extracted from code (@Making world-class docs takes effort | daniel.haxx.se) – you usually need to add richer descriptions, examples, and higher-level context that code comments lack. Think of auto-gen as a starting point or a supplement. **Mintlify's API Playground can be a great addition to MDX-based reference pages.** | |
| - **Make it accessible:** Provide search and indexing for reference material. **Mintlify provides excellent search out-of-the-box.** If applicable, offer an offline version. *Mintlify handles PDF generation, so this point is not directly applicable.* | |
| - **Examples in reference:** Although reference is mostly factual, including **short examples** of usage is highly beneficial. Many users look for a quick usage pattern. Even a one-line code snippet for an API function can clarify its use. In fact, “you can never go wrong by providing examples” in documentation (@Making world-class docs takes effort | daniel.haxx.se) – a reference page with no example might be ripe for improvement. (Just ensure examples in reference stay minimal and focused on demonstrating the syntax or output of that specific element.) **Use MDX components to enhance your examples.** | |
| ### 4. Explanations (Discussions and Background) | |
| **What it is:** Explanation (or **discussion**) docs are **understanding-oriented** write-ups that dig into **the “why” and “how” behind the scenes** (@Explanation - Diátaxis) (@Explanation - Diátaxis). These are the docs one reads to deepen their conceptual knowledge of the system or to gain insight into a concept, design decision, or piece of background information. They don’t necessarily tell you how to do a specific thing; instead, they *clarify* complex topics and answer questions like “Why does this work this way?”, “What’s the theory or concept here?”, or “How do these components fit together conceptually?” | |
| Common examples of explanation docs: **Architecture overviews**, **design rationale documents**, **conceptual guides**, **tutorials on underlying concepts** (as opposed to product tutorials). For instance, a machine learning library might have explanation docs on “How our model training pipeline works internally,” or “Concepts: Overfitting and Regularization,” or an article on the theoretical background of an algorithm used. These are things that **make sense to read even when you’re not actively using the product** (maybe even away from your computer, as Diátaxis humorously notes reading them “in the bath” (@Explanation - Diátaxis)). | |
| **How to write:** Explanations are usually written in an essay or article style. They can be longer form. The key is to keep them *focused on clarifying a specific topic*. Unlike reference, you **can be more discursive** – storytelling, analogies, examples, comparisons, and historical context can all be appropriate here to aid understanding. However, maintain clarity and don’t wander off-topic. Structure the explanation logically: start by stating the question or concept you will address, then break down the answer into sections. You might include diagrams or illustrations here since conceptual content often benefits from visualization. For example, in an “architecture overview,” include a system diagram with labels and then explanations of each component. **MDX allows you to embed diagrams and interactive components directly within your explanations.** | |
| **Tips:** | |
| - **Answer “Why” and “How”:** This is the place to answer “why does X do this?” or “how exactly does X work under the hood?” For example, if your reference says a function uses AES-256-GCM encryption, an explanation doc might discuss “Understanding our encryption scheme” – why that mode was chosen, what it means for security, etc. | |
| - **Keep it detached from immediate tasks:** Explanations generally don’t contain steps or procedures. If you find an explanation doc turning into a how-to, consider splitting it. It’s fine to include a short example to illustrate a point, but the tone is more “deep dive” than “recipe.” | |
| - **Use analogies and references:** If a concept is complex, try relating it to known ideas (but be careful with colloquialisms or culturally specific analogies that might confuse readers globally (@Good Docs Take Great Effort | er4hn)). Also, link out to external resources or academic references if readers want to learn more. **Mintlify's linking capabilities are helpful here.** | |
| - **Make it optional reading:** Explanation docs are often not required to use the product, but they *enhance* understanding. Make sure your getting-started and how-to guides don’t depend on a user having read the deep explanations. Instead, think of explanation docs as supporting material that advanced or curious users can consult. It’s important but usually less urgent than guides that unblock someone’s immediate task (@Explanation - Diátaxis). | |
| - **Examples of explanation content:** “Background concepts,” “FAQ or Q&A articles,” “Comparisons” (e.g., Your tool vs. alternatives), “Design decisions and trade-offs,” “Troubleshooting deep dive” (explaining common errors conceptually). You can label these sections in user-friendly terms (e.g., call the section **Concepts** or **Background** instead of just “Explanation” if that resonates more (@Explanation - Diátaxis)). | |
| - **Don’t skip them entirely:** Some teams focus only on tutorials/guides and reference, and assume users will figure out the concepts. However, providing explanation docs builds a fuller understanding and can turn users into power users. It’s not a luxury; “no practitioner of a craft can afford to be without an understanding of that craft” (@Explanation - Diátaxis), so include materials that help users grasp the bigger picture. | |
| By covering all four Diátaxis categories in your documentation set, you cater to **different user needs and scenarios**: learning from scratch, solving a specific problem, looking up a detail, and gaining deeper understanding. You can separate these in your documentation site structure (e.g., have sections or tags for Tutorials, Guides, Reference, Concepts) so users know where to go. **Mintlify's navigation and grouping features make this organization straightforward.** This separation also forces you as a writer to be clear on the purpose of each doc and write accordingly. The result is a more navigable, useful documentation hub. | |
| ## Writing Style & Clarity | |
| The content of your docs is only as good as how well it’s communicated. A poorly written guide can confuse or alienate readers even if all the right information is buried in it. This section covers best practices for **writing style, tone, and structure** that make documentation clear and developer-friendly. These principles, adopted by technical writers, will make your documentation easier to read and understand. Keep these in mind as you draft any doc: | |
| - **Be Concise and to the Point:** Developers usually read documentation with a goal in mind – they’re not looking for prose or entertainment. Respect their time by **cutting unnecessary words** and fluff (@Style & Tone - Mintlify Guides). Use short sentences and get to the point quickly. For example, instead of “In order to successfully complete the installation, you will first need to make sure that you have properly set up X,” just say “Make sure X is set up before installing.” Brevity is key, as long as clarity isn’t sacrificed. | |
| - **Clarity Over Cleverness:** Write in simple, direct language rather than trying to sound overly clever or technical. Avoid jargon and acronyms unless you’re sure the audience knows them – and if you must use them, consider briefly defining them. Prefer plain words over complex ones (e.g., say “use” instead of “utilize”). The goal is that a reader with the assumed background can understand without having to re-read sentences. Don’t write documentation like marketing material or academic papers; aim for a friendly, clear tone. *“Be simple, direct, and avoid jargon or complex sentence structure,”* as one guide advises (@Style & Tone - Mintlify Guides). | |
| - **Use Active Voice and Imperative Tone:** In instructional docs, speak **directly to the user**. Use second person (“you”) and active voice to make instructions clear (@Style & Tone - Mintlify Guides). For example, *“A configuration file should be created”* is indirect; instead: *“Create a configuration file.”* Active voice makes sentences easier to parse and gives clear direction on who should do what. It also tends to be more concise. When describing behavior, active voice clarifies the subject: e.g., *“The server **sends** a response”* is clearer than *“A response **is sent** by the server.”* | |
| - **Write for Scanning:** Most users don’t read docs top-to-bottom; they scan for the bits they need. Make your documentation **skimmable**. This means using descriptive headings and subheadings for sections, breaking content into short paragraphs, and using **bulleted or numbered lists** for discrete items or steps (@Style & Tone - Mintlify Guides) (@Good Docs Take Great Effort | er4hn). A wall of text is intimidating and hard to navigate. Instead, doc pages should be structured with plenty of visual breakpoints: lists, tables, code blocks, call-out notes, etc., where appropriate. Even within a paragraph, consider using **bold** or *italic* to highlight important terms when they first appear. But be careful not to overdo emphasis – it’s about drawing attention to key points. **MDX makes it easy to format text and create these visual elements.** | |
| - **Front-Load Important Info (BLUF):** Don’t bury the lede. In military writing this is called BLUF – “Bottom Line Up Front.” Give a summary or the key point at the **start** of each document or major section (@Good Docs Take Great Effort | er4hn). This helps readers decide if they’re in the right place and sets context. For example, if a section is about configuring SSL, the first sentence might be “**This section shows how to enable SSL encryption for the client, using a custom certificate authority.**” A reader skimming will immediately know what’s covered. Consider adding a brief intro that outlines what the guide will achieve or what the reference page contains. In longer conceptual articles, a one-paragraph abstract at the top can orient the reader. *Every section should start with a summary of what follows* (@Good Docs Take Great Effort | er4hn), so someone can grasp the gist without reading full detail (and then choose to drill in if needed). This also disciplines you to ensure each section has a clear purpose. | |
| - **Define the Intended Audience:** At the beginning of a doc (or even the whole documentation set), clarify who the content is for and what prior knowledge is expected (@Good Docs Take Great Effort | er4hn). This can be as simple as a note like “*This guide is intended for engineers who are familiar with database indexing; beginners may want to read the Introduction to Databases first.*” By stating the audience, you help readers self-select and you guide your writing depth. It prevents you from over-explaining to experts or under-explaining to novices. Knowing the assumed background (e.g., familiarity with Linux command line, or knowledge of certain terminology) also prevents confusion. Defining audience “removes uncertainties from the author about how much detail to go into” and keeps the doc focused (@Good Docs Take Great Effort | er4hn). | |
| - **Use Lists and Structured Steps:** Whenever you find yourself enumerating multiple items or instructions in text, consider using a list format. Lists make information easier to parse and refer back to (@Good Docs Take Great Effort | er4hn). Use **numbered lists** for step-by-step processes (so the user can easily follow “Step 1, Step 2,” etc.). Use **bulleted lists** for collections of related points, requirements, options, or tips. For example, listing supported operating systems or key features is much clearer as a bullet list than in a run-on sentence. Even when describing something conceptually, breaking it into bullet points can help emphasize each aspect. As ER4HN’s guide humorously illustrates, a descriptive paragraph can often be transformed into a list for clarity (@Good Docs Take Great Effort | er4hn). Each bullet should ideally contain one main idea. This chunking of information greatly aids readability in technical docs. | |
| - **Be Precise and Unambiguous:** Precision in language is crucial for technical documentation. Vague statements can confuse or mislead. Always prefer a specific term over a general one if it makes the meaning clearer (@Good Docs Take Great Effort | er4hn). For example, saying *“the data is encrypted”* is less useful than *“the data is encrypted using AES-256-GCM”* (@Good Docs Take Great Effort | er4hn). The latter tells the knowledgeable reader exactly what’s happening. If there’s something unique or non-obvious in your system, describe it explicitly. Avoid weasel words like “secure,” “optimal” without backing – specify *how* or *to what degree*. Along with precision, maintain an **objective tone** in reference-like material (stick to facts). If describing a limitation or undefined behavior, be upfront. It’s better the user knows exactly what to expect (or not expect). | |
| - **Maintain Professional Tone (Globally Understood):** Documentation can be friendly, but it should still be written in a professional tone suitable for a global audience (@Good Docs Take Great Effort | er4hn) (@Good Docs Take Great Effort | er4hn). That means avoiding slang, idioms, or cultural references that might not translate. For example, sports metaphors (“hit a home run”) or colloquial expressions (“in a pinch”) can confuse non-native speakers or simply feel out of place in docs (@Good Docs Take Great Effort | er4hn). Humor is often better left out of documentation, or used very sparingly, because what’s funny to one person might be confusing or even offensive to another. Also, refrain from being too casual or familiar; avoid phrases like “just easily do X” or “it’s super simple” – they can alienate readers if they *don’t* find it simple. Write as if addressing a respectful stranger, not a buddy. | |
| Additionally, address the reader as “you” and avoid referencing them in third person (don’t say “the user should…” – say “you should”). At the same time, do not assume the user is co-located or of the same background as you. For instance, avoid region-specific political jokes or references to local events (@Good Docs Take Great Effort | er4hn). Keeping a slightly neutral, instructional tone ensures the widest audience can follow along. This doesn’t mean being robotically formal; you can still be conversational (“Now that you’ve installed the CLI, **let’s create** your first project.”) – just avoid colloquialisms and maintain respect. | |
| - **Avoid “Duh” Documentation:** Don’t state the obvious or insult the reader’s intelligence with extremely basic statements (@Style & Tone - Mintlify Guides). For example, writing *“Click the **Save** button to save your changes”* is not helpful – the user can likely infer that. It adds noise and can frustrate readers. Instead, focus on where they might get tripped up or what isn’t intuitive. However, note this doesn’t contradict being beginner-friendly; it means find the right granularity. Telling a user to “open the Settings menu” (with maybe a screenshot or path) is fine, but spelling out that an OK button confirms an action is overkill. Ensure each sentence adds value. If a tester of your docs says “well, duh” to a line, consider cutting it. | |
| - **Ensure Technical Accuracy and Grammar:** This should go without saying, but always double-check your content for **correctness** (both technical and grammatical). *Spelling and grammar mistakes* in docs can erode trust in the product (@Style & Tone - Mintlify Guides). Users might wonder: if the company didn’t care to fix typos, did they test the code either? It reflects on quality. Use spell-checkers or tools like **Vale** or **Grammarly** to catch language mistakes. **Mintlify integrates with Vale to help enforce style consistency.** For technical accuracy, try out the documented steps or code as you write (or have them tested by someone) – nothing is worse than following docs and hitting an error because the instructions were wrong or out of date. | |
| - **Consistent Terminology and Notation:** Decide on standard terms and phrasing for your documentation and stick to them. Inconsistent terminology can confuse users (@Style & Tone - Mintlify Guides). If you call something an “**API Key**” in one page, don’t call it a “token” elsewhere unless it’s intentional and explained. Maintain consistency in how you capitalize or style certain words (e.g., error codes, product names). It helps to create a mini **style guide** for your product docs: e.g., “we say ‘workspace’ not ‘project’, use US English spelling, all command-line options are in code font, etc.” Many organizations use existing **Style Guides** from big tech companies as a baseline – for example, Microsoft’s, Google’s, or the [Splunk Documentation Style Guide] (@Style & Tone - Mintlify Guides). These cover conventions on everything from capitalization to phrasing. Adopting such a style guide (and even automating checks for it via a linter (@Style & Tone - Mintlify Guides)) can significantly improve consistency across documentation, especially in teams with multiple writers. **Mintlify's integration with Vale is extremely useful for enforcing a style guide.** | |
| - **Use Visuals and Examples Appropriately:** A picture can truly be worth a thousand words when explaining a complex concept or showing a UI workflow. Don’t shy away from **using diagrams, screenshots, or charts** to complement text, when they can convey something faster or more clearly (@Good Docs Take Great Effort | er4hn). This is especially useful in explanation or tutorial parts of docs. For instance, an architecture diagram can help users understand component relationships at a glance. Always add a **caption or alt-text** to images for clarity and accessibility (@Good Docs Take Great Effort | er4hn). The caption should explain what the image is showing if it’s not obvious, so someone skimming the doc can catch the context. Keep in mind that some will not see the image (screen readers, or if the image fails to load), so never put critical info *only* in an image – describe it in text as well. **MDX lets you easily embed images and even interactive components.** | |
| That said, **don’t use visuals as fluff**. They should serve a purpose (e.g., don’t insert random stock photos or abstract graphics that don’t add information). Too many screenshots of trivial steps can also clutter a guide. Use UI screenshots when instructing UI navigation, and diagrams for conceptual overviews or processes. If code output is visual (like a graph), showing it is fine. Remember to update images when the UI or output changes – stale screenshots can mislead. Diagrams may need revision as architecture evolves. | |
| - **Example-driven whenever possible:** Examples deserve special mention as part of writing style. Developers often learn and understand by example. Whenever you introduce an abstract description, consider following it with “for example: …” and a concrete snippet or scenario. In reference entries, include a quick example usage; in how-to’s, give example values or cases; in explanations, use hypothetical scenarios to illustrate points. Examples make the documentation less dry and give readers patterns they can mimic. Many programming languages (Go, Rust, etc.) even integrate examples into their docs which can be executed (@Good Docs Take Great Effort | er4hn) – showing how valuable this is. In your docs, an example could be as simple as a curl command sample for an API or a small code block demonstrating a function call with typical parameters. **Use MDX components to create rich, interactive examples.** Ensure your examples are **correct** and **idiomatic** (reflect best practices). We’ll talk more about keeping examples up-to-date in the maintenance section. | |
| - **Voice and Person:** As mentioned, use second person (“you”) for most docs. Avoid referring to the reader as “we” or “they.” Keep a helpful tone – you are the guide, and the reader should feel the docs are written for them (@Style & Tone - Mintlify Guides). Avoid phrases like “it’s easy to see that…” or “simply do X” – what’s simple to one might not be to another. Instead, just instruct or explain. When referencing your product or company, you can use “we” if appropriate (e.g., “In this guide, *we’ll* build a simple app…” is fine; it feels like author+reader are doing it together). But don’t overuse “we” in explanations that might blur who’s performing an action (reserve “you” for user actions and use passive or “the system” for system actions if needed). | |
| By following these style guidelines, you make your documentation not only accurate but *enjoyable* (or at least not painful) to read. A consistent, clear style builds user trust – readers can tell when docs are polished. As one tech writer noted, you may never get compliments for correct grammar or consistency, but users will definitely notice if those are lacking (@Style & Tone - Mintlify Guides). Good style is somewhat invisible – the user just smoothly understands the content without stumbling. Aim for that seamless clarity. | |
| ## Examples & Formatting: Making Documentation User-Friendly with MDX | |
| Great documentation is as much about *experience* as it is about content. This section focuses on how to present information in a way that is intuitive, easy to follow, and *useful* to the user, specifically leveraging the power of **MDX** within the **Mintlify** platform. | |
| ### Code Examples and Snippets | |
| **Why examples?** Because developers often learn by example, providing code snippets and sample outputs is one of the most helpful things you can do. As the saying goes, a lot of programming (and integration) happens by copying and adapting examples. Stack Overflow’s popularity attests to this, and indeed it’s been noted that copying code is a primary mode of development (@Good Docs Take Great Effort | er4hn). If your docs lack examples, users might turn elsewhere to find them. Always try to include examples for key use cases – in fact, if users keep asking for more examples, that’s a sign your docs need improvement (@Making world-class docs takes effort | daniel.haxx.se). | |
| **Best practices for examples:** | |
| - **Provide a Working Starting Point:** Every example should be as self-contained as possible. This doesn’t mean showing entire projects, but ensure that if a user copies the code, it won’t fail due to a missing piece that hasn’t been mentioned. For instance, if the example uses a certain library or requires an import, show that import (or explicitly state prerequisites above the snippet). A Twilio blog example demonstrated how a code snippet with a missing import and unspecified credentials confused users who copied it (@Don't Skimp on Documentation | Twilio). Don’t assume the reader will read explanatory text around the code – *many skip straight to the code block* (@Don't Skimp on Documentation | Twilio). Therefore, put crucial context either in the snippet or in immediate comments around it. It can be helpful to comment inline within the code for clarity (e.g., `// Replace with your API key`). **Use MDX components, like custom `<Note>` or `<Warning>` components, to add this context elegantly.** | |
| - **Use Realistic Values and Scenarios:** Make your examples relevant. Instead of foo/bar or dummy variables for everything, consider using realistic sample values that make the example concrete. E.g., demonstrate an API call to a real endpoint if possible, or use a plausible data input. This makes it easier for the reader to relate the example to their own use case. Of course, be mindful of not exposing any real secrets. When showing output, use realistic output too. If demonstrating a command’s output, show exactly what it would produce for the given input, so the user knows what to expect. | |
| - **Highlight Important Lines:** If you have a large snippet, you can highlight or call out the part that’s specifically relevant to what you’re explaining. This might be done via comments or notes in the text. For instance: *“In the example below, note how we pass the `timeout` parameter to the client – this is what triggers the retry logic.”* Then the code shows that line in context. **You could use an MDX component to visually highlight specific lines of code.** | |
| - **Show Expected Output or Behavior:** Especially in tutorials or how-to’s, if the user runs the example code, tell them what should happen. For a code snippet, you might show a sample output or log after it. For a UI action, describe what change the user should see. This helps confirm to the user that they did it right. For example: “Run this command. You should see output similar to: ```...```.” If the output is too long, excerpt the relevant part. | |
| - **Multiple Language/Platform Support:** If your product has SDKs in multiple languages or CLI vs GUI, provide examples in each major variant, or at least the most popular ones. **Mintlify's tabs feature is perfect for this.** This is great if you can manage it, as it directly serves a broader audience. If maintaining many parallel examples, ensure they all get updated together when the API changes (which is a challenge – consider automation or having language owners maintain their snippets). | |
| - **Interactive Examples:** MDX shines here. You can embed interactive components directly within your documentation. Consider using live code editors (like CodeSandbox embeds) or custom React components that allow users to interact with your API or product in real-time. This can significantly reduce friction for a user trying out your product. For instance, Go and Rust docs allow running examples in the browser (@Good Docs Take Great Effort | er4hn). At minimum, make examples copy-paste friendly (no hidden characters, use plain text code blocks with appropriate formatting, which Mintlify handles well). **Leverage Mintlify's API Playground where appropriate.** | |
| - **Test Your Examples:** Treat examples like code that needs to run. Many projects have been embarrassed by documentation that doesn’t actually work. If possible, include doc examples in your automated tests or CI. Some languages (like Go) let you write examples that double as tests. Others use doctest frameworks. If manual, at least run through them whenever you release. Stenberg enforced that every new curl command-line option must come with an example in the docs, and even added CI checks to ensure no new option lacks an example (@Making world-class docs takes effort | daniel.haxx.se) (@Making world-class docs takes effort | daniel.haxx.se). This kind of rigor ensures examples stay accurate. It’s worth the effort, because **broken or incorrect examples are worse than none** – they mislead and frustrate users. | |
| ### Page Layout and Formatting (with MDX and Mintlify) | |
| - **Structure each page for clarity and SEO:** As mentioned earlier, each documentation page should have a single clear **H1 title** (e.g., the topic or task name) (@Don't Skimp on Documentation | Twilio), and ideally a short introductory paragraph stating its purpose. Use hierarchical headings (H2, H3, etc.) to break content into logical sections. This not only helps readers navigate, but also improves search engine indexing of your docs. Ensure the page’s title and meta-description (if applicable) accurately reflect its content (@Don't Skimp on Documentation | Twilio) – e.g., a page titled “Using OAuth Tokens” with a meta description “How to authenticate API requests with OAuth tokens in XYZ API.” **Mintlify automatically generates SEO-friendly URLs and allows you to customize metadata.** This way, if someone searches the web for “XYZ API OAuth token,” your doc is likely to show up and clearly indicate relevance. | |
| - **Cross-link related content:** Within your docs, hyperlink generously to related pages or further reading. When you mention something that is explained elsewhere (another guide or reference entry), make it a clickable reference. Use descriptive link text (e.g. *“see the guide on sending emails”* instead of “click here”) (@Don't Skimp on Documentation | Twilio). This not only helps with SEO, but improves user navigation – readers can open the link if they need more detail on that sub-topic. Many users won’t navigate via a sidebar alone; they rely on in-text links to discover relevant docs. However, don’t overdo links such that every other word is blue – link the main concept or object. **Mintlify's automatic linking and `Link` component make this easy and consistent.** | |
| - **Emphasize important notes:** Use formatting or call-outs for **warnings, tips, and notes**. For example, if a certain step is dangerous (could delete data, etc.), put a **Warning:** in bold or a colored block if your system supports it. Similarly, “Note:” or “Tip:” highlights can draw attention to side information like performance tips or alternative methods. Visually distinguishing these helps users not miss them. **Use Mintlify's `<Callout>` component for this, or create custom MDX components for specific types of notes.** | |
| - **Code formatting:** Present code in proper code blocks with syntax highlighting (if your tooling supports it for the language). **Mintlify and MDX provide excellent code block support with syntax highlighting.** In-line code (like command names, file paths, or code references in a sentence) should be wrapped in backticks to distinguish them. For example: *Run the `init_database` script before starting the server.* Consistent code formatting makes the docs easier to read and shows clearly what is a literal command or value. Also, **don’t break lines oddly** in code blocks – ensure they scroll or use continuation characters so that what’s copy-pasted is exactly what’s intended. | |
| - **Tables and data:** If you need to convey comparative information or parameters, consider using tables for clarity. For instance, a table of configuration options with columns for “Name,” “Description,” “Default,” “Allowed values” can be easier to scan than a bullet list if there are many options. Just ensure tables are not too wide (break text or use multiple tables if needed for readability on narrow screens). **MDX allows you to use standard Markdown tables, or create custom table components for more complex layouts.** | |
| - **Images and diagrams:** Place images centered (if possible) and near the relevant text. Always include an **alt text** and/or caption describing the image (@Don't Skimp on Documentation | Twilio). If the documentation platform doesn’t show alt text as caption, mention the figure in text (e.g., “(see diagram above)”). Ensure images are optimized (small file size, proper format) so they load quickly; documentation sites should be lightweight. If showing UI, sometimes it helps to highlight the element (using an arrow or circle in the image) especially if it’s a screenshot of a busy interface. **MDX allows you to use standard Markdown image syntax, or create custom image components for more control.** | |
| - **Accessibility considerations:** Apart from alt text, ensure your formatting follows accessibility best practices: good contrast, not relying solely on color to convey meaning, using semantic HTML if applicable (headings, lists properly). This not only helps disabled users (e.g., screen reader users) but often improves overall clarity. **Mintlify is built with accessibility in mind.** | |
| - **Make docs easily **searchable**:** **Mintlify provides a powerful search function out-of-the-box.** If your documentation is delivered on a website, include a search function that indexes all docs. Many users will prefer searching within docs than navigating manually. Ensure that the search works well (check what keywords bring up, etc.). If your docs are in a repository (like markdown on GitHub), mention keywords in text if needed so that a repository search can find them (for example, if error messages are important, include them in troubleshooting docs so searching the error leads to the right page). | |
| - **Self-contained pages:** Reiterating Twilio’s point – assume each page might be the first (or only) thing a user reads (@Don't Skimp on Documentation | Twilio). So include necessary definitions or link back to introductions as needed. For instance, if a how-to guide is about an advanced feature, it might be worth one sentence: “*(This guide assumes you have completed the Basic Setup tutorial.)*” with a link. Or re-define a key term briefly if it’s important to understanding the page. This way, the user doesn’t get lost or have to hunt around for context. | |
| - **Offline and PDF docs:** *This section is less relevant with Mintlify, as it handles PDF generation automatically. You can focus on ensuring your content is well-structured for online consumption.* | |
| - **Internationalization:** If your audience is global and your company/resources allow, translating documentation or offering localized versions can be extremely helpful. Short of full translations, writing in simple English as mentioned (no idioms, etc.) already helps non-native readers. **Mintlify supports internationalization.** If you do translate, maintain those versions diligently with updates. | |
| In essence, treat the documentation site or pages like a user interface in itself: design it for ease of use. The content (what you write) is crucial, but so is presentation. A user should be able to quickly find answers, copy code, understand where to click or what to type, and trust that what they see is up-to-date and relevant. Strive for a documentation layout that is clean, organized, and consistent site-wide (common navigation, consistent style on all pages). **Mintlify provides a consistent, customizable theme and navigation structure, making this easy to achieve.** | |
| ## Maintaining Documentation: Versioning, Updates, and Automation with Mintlify | |
| Writing great documentation is half the battle; keeping it great is the other half. Software and its usage evolve, and documentation must evolve with it. Stale or incorrect documentation can mislead users and erode their trust faster than almost anything else. In this section, we cover how to maintain documentation over time – including version management, update processes, and tools to reduce the manual burden, **specifically focusing on how Mintlify can help.** | |
| - **Version Your Documentation:** If your software has versioned releases (especially with API changes), you should maintain version-specific documentation or clearly indicate version differences. Long-lived projects should note when features were introduced, changed, or deprecated (@Making world-class docs takes effort | daniel.haxx.se). For example, an API reference might say “*(New in 2.5)*” or have separate docs for v1.0, v2.0, etc. **Mintlify provides built-in versioning support, allowing users to easily switch between different versions of your documentation.** This prevents confusion when users on an older version read docs for a newer one (or vice versa). If maintaining multiple versions is too heavy, at least keep an archive of older docs accessible. In code comments or reference, you can annotate version availability inline as well. The key is to save users from guessing why something in docs doesn’t match their reality due to version mismatch. | |
| - **Docs and Code Together (“Docs-as-Code”):** **Keep documentation close to the codebase** whenever possible (@Making world-class docs takes effort | daniel.haxx.se). This is a widely recommended practice because it makes it easier to update docs as part of development. **Since you're using MDX, your documentation files *are* code (or at least, code-like). Store them in the same repository as your application code.** When a developer implements a feature, they can simultaneously update the relevant docs – or reviewers can ensure they did. Keeping docs in a separate place (like a wiki or separate site) often leads to them falling out of sync, since code changes and doc changes aren’t linked (@Making world-class docs takes effort | daniel.haxx.se). The closer (in workflow) that docs are to code, the higher the likelihood they’ll be kept accurate (@Good Docs Take Great Effort | er4hn). Some strategies include: | |
| - Write documentation in the same branch and have it go through code review. | |
| - If docs are user-facing but you want to keep them separate, at least have a policy: no code PR is complete without docs, and maybe the docs site auto-deploys from the main branch. **Mintlify integrates with Git, making this workflow seamless.** | |
| - Use tools that generate parts of docs from code (like docstrings to reference) to guarantee consistency, but remember to add human-written parts too as needed (per earlier advice). **Mintlify's API Playground can help with this.** | |
| - For internal docs (like design docs or runbooks), storing markdown in the repo and rendering it in a portal can work well. The ER4HN blog notes Markdown is a great choice for docs: easy to write and lint, yet offers some formatting (@Good Docs Take Great Effort | er4hn). **MDX extends Markdown, providing even more power and flexibility.** | |
| - **Documentation Testing & CI:** Just as we run tests on code, try to **automate checks on documentation**. Several approaches: | |
| - **Link Checkers:** Use a CI tool or script to scan your docs for broken links, images, or cross-references. Dead links make docs frustrating. **Mintlify provides some link checking functionality.** | |
| - **Spell Check / Lint:** Incorporate a documentation linter such as Vale (@Maintenance - Mintlify Guides) to catch style issues, banned phrases, or formatting problems automatically in each docs PR. You can enforce things like “use American spelling” or “don’t use passive voice” or “term X should appear instead of Y” if you want to be strict. **Mintlify integrates with Vale.** | |
| - **Example/Code Testing:** As discussed, if you have code examples, see if you can extract and run them as part of tests. Even if not full automation, have a process to run through tutorial steps after major releases to ensure nothing broke. **You can potentially use MDX's ability to execute code to help with this.** | |
| - **Build Warnings:** If you generate docs (e.g., with Sphinx or Docusaurus), treat warnings from the build (like missing references, or unused files) as errors to fix. **Mintlify provides build warnings and error reporting.** | |
| - **Enforce Updates:** Some teams enforce via CI that certain files (docs) must be updated if certain code changes are made. For example, if you modify an API signature in code, the CI might detect that and ensure the API docs file was touched in the same commit. This can be complex to set up but is powerful to prevent forgotten docs. At minimum, consider adding a checklist item in pull requests: “Docs updated?” which the reviewer must verify. | |
| - **Stale Content Detection:** Over time, some docs may not get touched because the feature is stable, but the world around it changes (e.g., external dependencies, screenshots of UIs, etc.). You can script a check for files not updated in, say, 12 months, and flag them for review (@Maintenance - Mintlify Guides). Alternatively, maintain metadata in docs for “last reviewed” and have a routine to review them periodically. **You could potentially use Git history and Mintlify's analytics to help with this.** | |
| - **Regular Reviews and User Feedback:** Recognize that you won’t catch every issue alone. **User feedback is gold** for documentation. Encourage users to report documentation issues – for instance, have a “Suggest edits” or “Report a problem” link on each doc page that opens a quick feedback form or a GitHub issue template. **Mintlify provides built-in feedback mechanisms, including the ability to open GitHub issues directly from the documentation.** For open-source projects, accept doc contributions just like code (maybe even label good first issues for docs). Stenberg emphasizes making docs easy to contribute to as an important factor (@Making world-class docs takes effort | daniel.haxx.se). If users can easily propose a fix (typo, clarification), it improves docs and builds community goodwill. Internally, you should also gather feedback: if support or sales engineers keep getting the same question, that’s a doc that needs improvement. Set up a process with support teams to funnel common Q&A into doc updates. | |
| - **Prioritize Key Docs for Maintenance:** Not every single page needs equal attention all the time. Focus on the **high-impact docs** – e.g., your getting-started guide, the most visited how-to’s, etc., should be kept *especially* up-to-date and polished (@Maintenance - Mintlify Guides). **Mintlify's analytics can tell you which pages get the most hits.** Ensure those are never stale. Lesser-used docs can be updated when touched, or perhaps be marked as covering an older version if that’s the case. If you have dozens of guides, consider a maintenance rotation or assigning owners for sections of docs. | |
| - **Content Lifecycle and Rewrites:** Over years, docs can accrete “barnacles” – lots of notes, edge cases, historical asides, which might clutter the main narrative. If you find a guide becoming a Frankenstein of patchwork fixes, consider a periodic cleanup or rewrite (@Maintenance - Mintlify Guides). It’s often more efficient to rewrite a messy document from scratch than to keep editing line by line. Aim to do major documentation overhauls at logical points (e.g., a big version release, or when you notice increasing confusion). Plan these as you would a project: identify which areas need refactoring (maybe via an audit, as Mintlify suggests (@Maintenance - Mintlify Guides)), then tackle them in a focused sprint. Don’t be afraid to remove outdated sections – *wrong or misleading documentation is worse than none* (@Maintenance - Mintlify Guides), since it can send users down a false path. If something is truly obsolete and likely to cause confusion, it’s often better to *remove or archive* it than leave it up with incorrect info (@Maintenance - Mintlify Guides). | |
| - **Documentation Version Control and Releases:** Use version control (Git) for docs so you have history of changes, can revert if needed, and can track contributions. **Mintlify integrates seamlessly with Git.** Some teams tie doc deployments to product releases – e.g., whenever a new software version is released, the docs are published at the same time. This synchronization is ideal. Clearly indicate the doc version or release date on the site, so users know how current it is. **Mintlify handles versioning and deployments automatically.** If your docs are continuous (updating frequently outside of version releases), consider a changelog for documentation or at least highlight “What’s new” in docs if something significant was added (like a new guide). | |
| - **Leverage Tools and Platforms:** **You've already chosen a great platform: Mintlify!** Modern documentation platforms (like ReadTheDocs, Docusaurus, MkDocs, Mintlify, etc.) provide features to ease maintenance: built-in search, versioning, translation support, feedback widgets, and so on. Choose a system that fits your team. For example, if docs are written mostly by engineers in markdown, a git-based static site generator might work well. If you want non-engineers (PMs, tech writers) to easily edit, a wiki-like or headless CMS approach might help (though watch for drift from code). Some services integrate with code to auto-update API references (pulling from OpenAPI specs, for instance (@Maintenance - Mintlify Guides)). Consider using these to automate the tedious parts. But always budget time for the *human* aspects of docs that tools can’t do – clear explanations, organizing content, etc. **Mintlify provides many of these features out-of-the-box, and its MDX support allows for extensive customization.** | |
| - **Documentation Design Docs:** A meta tip – when planning a large new feature or module, write an internal design doc and include what the user docs will need. This ensures you think about usability. Some engineers practice writing the user-facing docs *as part of* the design review. It’s a great way to flush out unclear areas. ER4HN suggests always making design docs for anything non-trivial (@Good Docs Take Great Effort | er4hn), which indirectly helps produce better external documentation since you’ve reasoned through the feature thoroughly. | |
| In short, make documentation maintenance a **habit** and part of your project’s rhythm. A little continuous effort (updating as you go, automating checks) will save you from massive doc debts later. And remember, documentation quality can degrade if not tended, so treat it as you would treat code quality – with ongoing vigilance. **Leverage Mintlify's features to streamline this process.** | |
| ## Common Pitfalls to Avoid | |
| Even well-intentioned documentation efforts can go astray. Here are some common pitfalls in software documentation and how to avoid them: | |
| - **Skipping Docs or Writing Them Last-Minute:** Perhaps the biggest pitfall is not writing documentation at all, or doing a rushed job right before release. As discussed, this leads to poor quality docs (if any) and frustrated users. Avoid this by adopting a docs-first or docs-parallel approach. Lack of documentation will silently harm your project’s adoption (@Good Docs Take Great Effort | er4hn). Don’t treat docs as an afterthought – or you’ll end up with either no docs (making your project unusable for many) or low-quality docs that “waste the user’s time” just as much as none (@Good Docs Take Great Effort | er4hn). | |
| - **Only Auto-Generated Reference, No Guides:** Relying solely on code-generated docs (like Javadoc/Doxygen output, or an OpenAPI spec) and calling it a day is a mistake. This gives you the *skeleton* (function lists, parameters) but misses context, examples, and “how to actually use this” guidance. Users confronted with only raw reference often feel lost. As Daniel Stenberg noted, the best documented projects **don’t** rely only on docs extracted directly from code (@Making world-class docs takes effort | daniel.haxx.se). So ensure you write human-oriented docs (tutorials, how-to’s, conceptual guides) to complement the reference. Auto docs are fine for completeness, but insufficient for a gold-standard documentation on their own. | |
| - **Not Defining Audience or Scope:** If you don’t specify who a document is for, you might end up writing content that’s too advanced for beginners and too basic for experts – simultaneously alienating both. Each doc should target a certain user profile or use-case. Without this, your documentation may include either too much assumed knowledge or spend too much time on fundamentals unnecessary for the target reader. For example, a guide for *“experienced DB admins configuring replication”* will read very differently than one for *“new developers setting up the app for the first time.”* Define this up front to yourself (and optionally in the doc for readers) to avoid misalignment. | |
| - **Disorganized or Monolithic Docs:** A common pitfall is a giant, monolithic documentation page that tries to cover everything in one long narrative. This is hard for users to navigate (no clear sections, overwhelming length) and hard to maintain. Avoid the “one big page” syndrome (@Good Docs Take Great Effort | er4hn). Break out content into logical sections or separate pages (as per the Diátaxis structure). Also, have a clear navigation structure or index. **Mintlify's navigation features and automatic table of contents help prevent this.** If users can’t quickly find the section they need, they might give up. The opposite issue can also occur: too fragmented docs with no overview, but usually erring on side of modular is better as long as indexing is good. | |
| - **Outdated or Incorrect Information:** Documentation that no longer matches the software is dangerous. For example, an option that was removed still appears, or an old command that changed syntax. This will confuse and frustrate users, and as Mintlify said, *wrong docs can be worse than no docs* (@Maintenance - Mintlify Guides). To avoid this, tie docs updates to code changes rigorously. Archive or mark obsolete content clearly (or remove it). Regularly test doc instructions against the current software. If you know something is wrong and can’t update it immediately, at least put a warning banner that it’s outdated, so users are warned. **Use Mintlify's callouts for this.** | |
| - **Lack of Examples:** As emphasized, not providing examples (or providing poor ones) is a pitfall. If users never see how to actually use a function or feature, they may not figure it out or may use it incorrectly. Always ask “can I add an example here?” When you describe an abstract concept or a function, think of demonstrating it in action. If you have no examples due to time, consider that a to-do; if your product has users asking basic usage questions, that’s a sign the docs need more examples. | |
| - **Too Much Jargon and Internal Language:** Using internal code names, abbreviations, or domain-specific jargon without explanation will lose readers. Your documentation should be understandable to the target audience *without* requiring them to know your team’s internal vocabulary or highly esoteric terms. If your docs are filled with things like “our FOOBAR™ technology uses a flux capacitor approach” without explaining, that’s a problem. Translate internal terminology to user-friendly language, or explicitly define it in a glossary or introduction. Also, consistency matters here – if you call a concept “session” in one place and “login token” in another accidentally, users might think they’re different things (@Style & Tone - Mintlify Guides). | |
| - **Inconsistent Terminology or Style:** This goes hand-in-hand with the above. If different parts of the docs use different words for the same thing, or follow different formatting styles, it looks unprofessional and confuses users. For instance, one page says “Press Enter,” another says “hit Return key,” and another says “strike the Enter key” – these should be standardized. Establish and enforce style guidelines to avoid such inconsistency (@Style & Tone - Mintlify Guides). Also ensure units, formats, notations are uniform (e.g., don’t sometimes write ms and sometimes milliseconds arbitrarily). | |
| - **Overloading One Doc with Multiple Purposes:** Be cautious not to turn what should be a how-to guide into a mixture of tutorial + how-to + explanation. Each doc should have a clear purpose. If you find a single page doing “step-by-step instructions” and then diving into deep theory and then listing API endpoints, that’s a sign it should be split into separate docs. Mixing the Diátaxis types can make it hard for readers to follow. It’s okay to link between them (e.g., a tutorial links to an explanation article for curious readers), but don’t mash them together. | |
| - **Burying Critical Information:** Important notes—like security considerations, system requirements, version incompatibilities—should be highly visible, not hidden in a paragraph. A pitfall is to mention a crucial step only in passing or in text that users might skip. For example, if an installation must be done as admin, don’t only mention that at the very end; highlight it up front. Use call-outs for these things. **Use Mintlify's `<Callout>` component.** If many users make a common mistake, ensure the docs warn against it in the right place (before they would make it). This avoids frustration and support tickets. | |
| - **Assuming Too Much or Too Little:** Striking the right balance in assumed knowledge is tricky. If you assume too much, beginners will be lost (e.g., using an acronym or concept they’ve never heard of without any explanation). If you assume too little, experts will be annoyed (e.g., spelling out basic programming concepts in an advanced guide). The pitfall is not calibrating this per document. That’s why *Defining Audience* is important. If you get feedback like “I have no idea what this term means” from newbies, add a brief explanation or link. If you hear “this doc spends forever on basics I know,” perhaps it’s aimed at the wrong audience or should be split. Beta-testing your docs on a few people of varying experience can catch these issues. | |
| - **Poor Navigation and Findability:** If the doc structure is not intuitive, or there’s no search, users can’t find what they need. This is more a docs site design issue, but still a pitfall: you might have great content that nobody finds. **Mintlify provides excellent navigation and search out-of-the-box.** Mitigate this by providing clear navigation (table of contents, well-organized sidebar) and possibly multiple paths to find something (by task, by API, etc.). Also ensure each page has meta tags or mentions synonyms of things (e.g., if people might search a different term, include it or mention it). For example, if your product name changed, mention the old name somewhere for those still searching it. | |
| - **Neglecting to Update Examples and Screenshots:** Code examples or screenshots can become outdated as the product changes (APIs updated, UI redesigns). Outdated examples can lead users astray (imagine an example that calls a function that no longer exists). This pitfall is common when docs aren’t maintained vigorously. The solution: treat examples as testable, and set reminders to periodically review screenshots or UI instructions when a new version comes out. If a screenshot is old but you can’t update immediately, at least remove it or add a note that UI may have changed. | |
| - **No Feedback Mechanism:** If users encounter an error or something unclear in docs and have no way to report it, the docs won’t improve. The pitfall is thinking your docs are fine because no one said anything – maybe they just silently struggled or gave up. Always allow an easy way for users to provide feedback on documentation (a one-click rating, an edit suggestion link, a community forum). **Mintlify provides built-in feedback mechanisms.** | |
| By being aware of these pitfalls, you can watch out for them as you write and review documentation. In practice, after writing a doc, it’s good to do a self-check or peer review against some of these: “Did I assume too much? Is anything outdated? Is this too verbose? Is there an example? Is important info emphasized?” A little extra attention here can save a lot of user frustration down the line. | |
| ## Conclusion: Embrace a Documentation-First Mindset | |
| Great documentation doesn’t happen by accident – it’s the result of a conscious, sustained effort and a culture that **values documentation**. As we’ve seen, writing high-quality docs involves careful thought about the audience, structure, and clarity, as well as ongoing maintenance. The benefits, however, are enormous: easier onboarding of new users, fewer support issues, and a stronger reputation for your software. Users often judge a product by its docs before even trying the code. Clear, helpful documentation signals that you care about their success. | |
| Adopting a *documentation-first mindset* means you start thinking about docs at the very inception of a project or feature. You design APIs that will be easy to document (often, if it’s hard to explain in docs, that’s a clue the design might be too complex!). You perhaps write the README or outline the docs as a way to validate your design. You ensure that when code changes, one of your first questions is, “do the docs need to change?” Over time, this habit makes documentation an integrated part of development rather than a dreaded chore. | |
| Encourage your team to take pride in documentation. Celebrate improvements or user praise about docs just as you would celebrate a successful feature launch. Conversely, treat doc bugs with the same seriousness as code bugs. For AI assistants that help generate documentation, ensure they are guided by the principles in this guide – they should output text in the clear, structured manner we’ve described, but a human should always verify the accuracy and tone. **When using AI assistants with MDX and Mintlify, guide them to leverage Mintlify's components and features appropriately.** | |
| In summary, **don’t skimp on documentation** – it is as important as the code itself for technical products. As one engineer wrote, “writing effective documentation requires you to understand who your user is, how they behave, and how they find answers... and to dedicate time in your product development cycle” to produce docs that enable users (@Don't Skimp on Documentation | Twilio). It may take effort to reach “world-class” status, but every improvement will be appreciated by someone trying to learn or use your software. By following the best practices in this guide – structuring content by purpose, writing with clarity, providing ample examples, and keeping the docs up-to-date – you set your project up for a wider and more satisfied user base. **And by using MDX and Mintlify, you have powerful tools to create a truly exceptional documentation experience.** | |
| Finally, remember that **documentation is a continuous journey, not a one-time task**. Keep listening to your users, refining your guides, and iterating on the docs just as you iterate on the software. In doing so, you’ll build a culture of excellence in documentation that benefits everyone: users get what they need, and you get a thriving community with fewer hurdles. Documentation done right is a superpower for your project – invest in it, and it will pay dividends in user success and adoption. Happy writing! |
